Barbier's system was difficult, but it gave Louis on idea. He worked
night after night to make a simple system with dots. By age fifteen, he
had finished his system. He showed it to other students in the school,
and they loved it. They called it Braille, after him. At age seventeen,
Louis graduated from the school and become a teacher there. In his free
time, he copied books into Braille. Someone read to Louis while he
made the dots. He copied the books of Shakespeare and other writers
into Braille. The students read all the books and wanted more. The
school did not want a fifteen-year-old boy's invention to be better than
their own heavy books and would not let students read Braille books.
Nevertheless, the students continued to read them. Finally, after twenty
years, the school agreed to use Braille.
